Anti-Hosni Mubarak protesters use an Egyptian Army tank as cover during clashes between Anti-Hosni Mubarak protesters and Mubarak supporters in the area around Tahrir square February 03, 201 in Cairo, Egypt. Throughout the clashes, the army took a mostly neutral stance, trying to keep the two groups separate when they could, but often pulled back and watched when the clashes became too heated. .Photo by Scott Nelson
